as much as I hate ADC's, thornmail just shouldn't be a viable item
if it becomes a viable item it means the ADC's get forced to either:
- not attack you, that will make bruisers even worse or
- get forced to rush a armor penetration item and lifesteal which then results in the thornmail being useless
the fact that it's a passive is what makes me think it shouldn't be allowed to be viable because there is no down time on it.
to kite indefinitely?
